11 Claims. This invention relates generally to therapeutic preparations and the processes for manufactur- In my co-pending application Serial Number 623,393, filed July 19, 1932, there is disclosed a therapeutic remedy which has been found particularly useful in the control of coccidiosis, and a process for its manufacture. During the course of extensive use of this material it has been found that it is not as palatable as is desired, and in certain instances it releases its active ingredients at too rapid a rate while passing by the active ingredients are released at a more gradual and regulated rate.

Further objects of the invention will appear from the following description in which the preferred embodiment of the invention has been set forth in detail in conjunction with the accompanying drawings. 1

Figure 6 isa flow diagram, showing the principal steps in carrying out my process. Before describing the apparatus illustrated in the drawings, it may be explained that my process consists in general of combining an active therapeutic compound, like an iodo-nicotine tannate-proteincompound, with coagulated casein.

' A This material, preferablyafter being treated to remove undesired odors, is'then atomized and dried to. form a powder. The powder is then mixed with a suitable waxy material such as hy-. drogenated vegetable oil, after which the mixture is atomized and chilled.

The apparatus of Figure 1 is for the purpose of carrying out certain of the mixing operations,

and for effecting drying to form a granular material. It consists generally of a treatment chamber l0, erected upon the floor H, and provided with a door I2 for convenient access. Mounted upon the top 13 or platform, there is a mixing apparatus consisting of a receptacle l4, carried by horizontal trunnions l6. Within the receptacle l4 there is a rotary beater or agitator I! which is adapted to be driven by suitable means, such as an electric motor l8, through the reduction gearing l9. The drive gearing may be provided with a clutch, to be controlled by lever 2|. Inorder to manually tilt the receptacle l4 to discharge its contents, a shaft 22 is shown provided with a pinion 23 which engages a gear rack 24 secured to the receptacle.

The upper portion of chamber I0 is in communication with an inflow conduit 26, through which a suitable drying gas, such as air at a suitable temperature, can be introduced. Mounted centrally upon the floor ll, there'is a supporting column 21, upon the upper end of which is mounted a motor 28 Mounted upon the vertical shaft of this motor there is a rotary atomizer 29, which -is of such a character that it will break up a coagulated mass into small particles. In order to supply material to the atomizer 29, a depending conduit 3| is shown, having its upper opening through the top l3 and its loweropen end depending into the atomizer 29.

A suitable type'of atomizer 29 has been shown I in detail in Figures 3 and 4. This device consists of a pair of vertically spaced annular plates y 33 and 34, connected by circumferentially spaced vanes 36. Plate 33 is provided with a hub 31, which in turn is secured to the motor shaft 38.

Whilethe vanes 36 are substantially prpendicu- 'conduit 3| extends downwardly through the upper annular plate 34, as-shown in Figure 3.

' Assuming that this device is rotatedat a relative- 1y high speed, coagulated masses of wet material dropped down through conduit 3|; are thrown outwardly by centrifugal force and are impacted with vanes 36, thus serving to subdivide the material into relatively small particles. These particles are then distributed or thrown outwardly into contact with the drying gas maintained in treatment chamber III.

For the continual movement of gas from the interior of chamber I0, I have shown a conicalshaped exhaust box or cyclone separator 4| which can surround the supporting column 21. upper portion of this exhaust box is provided with tangentially-directed louvers 42, and the a treatment chamber 44 mounted upon the floor II and provided with a side door 46. Mounted upon the top wall of platform 41, there is a mixing apparatus consisting of a drum 48, carried by the trunnions 49. This drum is"adapted to be rotated by suitable means, suchwas an,,electric motor 5|, operating through the gearing 52. A clutch interposed in the drive gearing can be controlled by lever 53. The drum is provided with a charging door 54 and with electrical heating elements 56. Likewise, a well 51 is provided, through which melted wax can be introduced into the interior of the'drum.

Located within the treatment chamber 44 there is a rotary atomizer 58, similar to the atomizer 29 of Figure 1, which is driven by an electric motor 59. Material is supplied to the atomizer 58 through conduit 60 which has its upper end opening through the top 41. Located near the central vertical axis of the chamber, and adjacent the fioor ll, there is a box 6|, provided with tangentially opening louvers 62. This box is connected to a conduit 63 through which a. stream of cold air can be introduced. The upper portion of the treatment chamber is in communication with an exhaust conduit 64, which may lead to a cyclone separator.

My complete process in its preferred form, and the manner of utilizing the apparatus described above, can now be explained in detail as follows:-I first prepare an iodo-nicotine-tannateprotein compound, in accordance with the procedure outlined in said co-pending application Serial Number 623,393. Briefly, 50 pounds of soy bean (which is a source of protein in the form of glycinin) are soaked in water for ten hours and then ground into a thick liquid milk. This is then filtered to remove coarse particles and fibrous materials, and a certain amount of molasses may be added to flavorthe final product. The homogeneous filtrate is then heated to about 195 Fahrenheit and divided into two equal portions.

To one portion of the soy bean milk is added a solution of 25 lbs. iodine in 30 lbs. 95% alcohol,

while the milk is being constantly stirred. At

v this time glycinin, which constitutes about to of the protein content of the soy bean milk, combines with part of the iodine; the

starch in the milk combines with another partof the iodine, and the rest of the iodine is absorbed throughout the brown colloidal precipitate which is being formed in the process.

To the other portion of the soy bean milk there is added 38 lbs. of tannic acid (95% pure). The tannic acid is added gradually and the milk con- The tinually stirred. A yellow precipitate of glycinintannate is formed. About 1'7 lbs. of 95% pure nicotine is then added with continuous stirring. A dark viscous mass of nicotine-glycinin-tannate is formed.

The iodine protein compound with absorbed iodine made from the first portion of the soy bean milk, is now mixed with the nicotine compound made from the second portion of the milk, at about Fahrenheit. An additional reaction occurs to form an iodo-nicotine-tannate-protein compound, or, more specifically, a di-iodo-nicotine-glycinin-tannate. The brownish black precipitate formed, being a colloid, has no clear-cut physical characteristics, although it has been found possible to isolate therefrom a pure iodonicotine tannate-protein compound.

The mass of material prepared as described above is then intermixed with a suitable filler, such as finely ground corn meal, to form a moist powdery mass. This mass is then introduced into the mixing container 14 of Figure 1, and to it is added a powdered sodium-caseinate, in suitable proportions, such as 200 lbs. of the iodo-nicotinetannate-protein compound to 10 lbs. of sodiumcaseinate. After these ingredients have been thoroughly mixed together to cause the sodiummass is being mixed. The casein precipitates in the form of grains which mechanically retain within them the iodo-nicotine compound. As will be presently explained, the iodo-nicotine compound so retained by precipitated casein avoids the disadvantage of an objectionable taste.

After forming the casein precipitate as described above, I preferably further treat the material for the purpose of absorbing objectionable odors. I found that this can be accomplished by introducing into the mixer an absorbent material like charcoal, diatomaceous earth, and the like. Thus, in actual practice, from 5 to 10 lbs. of such material is added to the batch and intermixed therewith for a length of time sufficient to absorb the odors which it is desired to eliminate.

The material within the mixer is now in the form of a moist friable mass. This material is then removed from the mixer and fed downwardly through the conduit 3| of the apparatus shown in Figure 1, to be broken up into small particles by the action of the atomizer 29. While the particles settle downwardly within the treatment chamber Ill, considerable moisture is evolved, and further moisture is evolved from the material resting upon the floor. terial is collected upon the floor, but a certain amount of finer material is separated out in the exhaust box 4|.

The dried material produced as described above is then removed from the apparatus of Figure 1 and is introduced into the mixing drum of Figure 2, together with a suitable waxy material. Beeswax canbe used for this purpose, but I prefer to employ a hydrogenated vegetable oil which will harden at ordinary temperatures, because such an oil is digestible. In practice, about lbs. of the dried material is introduced into the drum 48, together with about 40 lbs. of the waxy material which has previously been melted and which is introduced through the well 51. By virtue of the electrical heating coils 56, this batch of mate- The majority of the ma-' which time the particles of the material removed 7 The material which settles to the floor ll of the chamber 44, and the material which may be recovered in the pneumatic separator connected to conduit 64, arenow completely processed and in the form of a granular powder.

The process described above has been summarized in graphic form by thefiow sheet of Figure 6.

It is evident that the product produced by the process described herein is superior to the product produced by the process of my co-pending application Serial Number 623,393. The material is highly palatable, since the casein avoids an unpleasant taste, and because objectionable odors are removed by the process. Since both the waxy material and the casein are digestible, the active ingredient carried by the material is gradually released within the intestines, with resulting destruction of-various intestinal parasites, including coccidia organisms and worms. The waxy material is digestible only in the intestinal tract, thus avoiding any release of the active ingredient in the stomach. The controlled release of the active ingredient makes possible destructive action upon organisms affecting the lower intestinal tract, and also minimizes toxicity and permits the administering of larger doses.
